A food web is the natural interconnection of food chains and generally a graphical representation of what-eats-what in an ecological community.
Why is a food web is a better depiction of energy flow in ecosystems?
Food webs illustrate how energy flows directionally through ecosystems, including how efficiently organisms acquire it, use it, and how much remains for use by other organisms of the food web. … Without these organisms, energy would not be available to other living organisms and life itself would not be possible.
Why are food webs more accurate than food chains?

For that reason, the term food web is more accurate than is food chain.
Why a food web tells us more about an ecosystem than a food chain?
A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before. … Since a food chain is much more simplistic than a food web, it can be used to predict the response of an ecosystem due to changes in population of a single species.
Why is a food web a more accurate depiction of nature than a food chain or pyramid?

Why is a food web more accurate than a food chain and describe how energy is transferred throughout an ecosystem?
The Food Web shows more of the interactions between the organisms of the ecosystem and the trophic levels included from Producers to Primary/Secondary Consumers up through the Tertiary Consumers. While a food Chain is more of a linear representation of a specific line of interaction within the greater Food Web.
